The study explored the effectiveness of four types of verbal glosses in terms of reading comprehension and incidental vocabulary learning and retention among 95 Iranian undergraduate university students. There were two instances of each of fifteen target words in the text. The gloss types included L1, L2, bilingual, and mixed glosses. With the mixed gloss type, for the first annotation the readers viewed both L1 and L2 definitions of the target word; the second annotation involved the sentence in which the target word appeared for the first time. Having read a short story, the participants took a reading comprehension and two word recognition tests, one immediately and the other two weeks later. The results overall disclosed the effectiveness of glossing compared with non-glossing. No difference was detected between L1 and L2 glosses, though the participants preferred the former to the latter. And finally, mixed glosses appeared to be the most advantageous gloss type. The findings and their implications will be discussed.
